  1. Dan,

    I'll assume you're asking about round pushers. Normally, the push pin is unscrewed from the outer round pusher from the inside of the case after the movement is removed. The round pusher on the outside of the case is serated (sp?), fits into a tube that protrudes from the case, and will not rotate. The push pin will normally have a screwdriver slot if it is not too worn. Once the push pin is unscrewed (you will find a spring and o-ring in there, too), the pusher will pull off from the outside. All I have worked on are standard right hand thread.

    The tubes should unscrew to the left. Are you going to save them or are you planning to replace them.
    They can be difficult to get out without damaging. If you are going to replace them, the easiest way to remove them is to drive a 3 corner broach inside and use the broach to remove. If you are planning to save them, you might want to heat them up with a hair drier to loosen any lock-tite that is on the threads (that is with the movement out).
